Save file won't load after update

StarSimUltra93​  Did you in fact try the clean user folder?  I ask because the Sims 4 errors in your dxdiag are very generic but can be related to bad mods or custom content, and also to a corrupt save.  So if you haven't already tried a new save in a clean folder, please do so now.  If it helps, try loading your main save in the new folder, still with nothing else added back.

Another cause of AppHangB1 errors is a bad graphics driver.  So if you can't even load a new save, please look for an update for the driver.  Go here:

Enter your serial number, choose your OS (just Windows 11 is fine) if prompted, click All Drivers, expand Driver-Graphics, and download the newest AMD driver by version number, if it's newer than your current one (31.0.21914.8004).  The first number matters most, e.g. 32 is newer than 31; after that, the last four numbers matter.

If you do find a newer driver, run the installer as an admin: right-click the download and select "Run as administrator."  Restart your computer afterwards and before trying to play.
